Well yes, but not as the only security mechanism, as far as I'm aware.
Barclays for example allows you to log in with this plus a separate pass code, but you can't do much damage without using a chip and pin reader that will give you an 8 digit one time pad too (alternatively they now let you use a mobile app to generate the one time pads)
E.g. you can't do transfers to recipients you haven't specifically saved for future payments, for example, without entering your pin, the account number and amount into your key generator and entering the resulting code into online banking.
